Is roentgenium shiny or dull?
D. Roentgenium (Rg) is element 111 on the periodic table. Few atoms of this synthetic element have been produced, but it is predicted to be a dense, radioactive metallic solid at room temperature.
Where is roentgenium found on Earth?
Roentgenium was discovered in 1994 by scientists at the Heavy Ion Research Laboratory in Darmstadt, Germany.
Is roentgenium a conductor?
Roentgenium is in the form of a solid metal. Elements which are classified as transition metals have the physical characteristics of being ductile, malleable, and are good conductors of electricity and also heat.
Who discovered Roentgenium 111?
scientist Wilhelm Conrad Röentgen

Is radon a solid liquid or gas?
Radon is a colourless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen. The gas liquefies at −61.8 °C (−79.2 °F) and freezes at −71 °C (−96 °F). On further cooling, solid radon glows with a soft yellow light that becomes orange-red at the temperature of liquid air (−195 °C [−319 °F]).

Where do they get helium?
Helium is the only element on the planet that is a completely nonrenewable resource. On Earth, helium is generated deep underground through the natural radioactive decay of elements such as uranium and thorium.
What are five uses for helium?
10 Uses for Helium: More Than Balloons and Blimps
- Heliox mixtures in respiratory treatments for asthma, bronchitis and other lung deficiencies.
- MRI magnets.
- High speed Internet and Cable TV.
- Mobile phone, computer and tablet chips.
- Computer hard drives.
- Cleaning rocket fuel tanks.
- Microscopes.
- Airbags.
Why is helium used in hospitals?
This rare element is critical to medicine where ultra-low-temperature liquid helium is used to cool the superconducting magnets in MRI scanners. About a third of all produced helium is used in these medical instruments with industrial applications using up most of the rest.
What do people use for helium?
Helium is used for medicine, scientific research, arc welding, refrigeration, gas for aircraft, coolant for nuclear reactors, cryogenic research and detecting gas leaks. It is used for its cooling properties because of its boiling point being close to absolute zero. This makes it attractive for use in superconductors.
